Shortfill are bottles of e-liquid that has 0Mg nicotine content. They are also not filled to the top, hence the term “Shortfill”, this is so that you can pour in a bottle of Nicotine Shot, to give you the desired Nicotine strength should you desire.
You can either vape them straight out of the bottle or purchase a Nic Shot to go with them. Nic shots come in 10ml bottles and can be of varying PG/VG ratio.
Generally speaking Shortfill e-liquid has a High VG content. This means that you create greater volumes of vape, which in turn increases flavour compared to 10ml bottles of 50/50 PG/VG. So a lot of users move onto High VG Shortfill to chase greater and more satisfying flavours and vape. This does come at a price however, because you are producing a large amount of vapour you will spend more money on e-liquid, however for many people it is a price worth paying once you discover your favourite flavours at the right Wattage!!
